I have had experience with Clarocet and was so impressed that I now import it from the States and sell it in this country as no one was selling it over here. my son suffered form acute anxiety from the age of 15 and antidepressants just made him feel rotten. I found Clarocet when he was 19 and it made such a difference to him. We noticed straight away if he missed it. Other people I have recommended it usually found it helpful and we have lots of people who buy it regularly.
To answer your question, NRI is best for anxiety and panic attacks, ERT for depression. We are in the process of rewriting the web site to make that clearer.
I hope that helps.
